Night workers and frequent fliers may be at increased risk of diabetes, according to a US study.

Researchers also said, little sleep and erratic sleep easily upset a person’s circadian rhythm, or “biological clock”, impairing insulin secretion by the pancreas and resulting in a build-up of sugar in the blood. High blood sugar levels can trigger diabetes. Participants in the study also had a decreased resting metabolic rate, which is conductive to obesity.

The research team, led by neuroscientist and sleep researcher Orfeu Buxton, observed the 21 participants for nearly six weeks in the hospital. They regulated when and for how long the participants slept and also what they ate.

Sleep deficiency and “circadian disruption” decreased participant’s’ resting metabolic rate, meaning their bodies burned fewer calories when they were inactive.

They also found increased glucose concentrations in the blood after meals, which they said was likely due to inadequate pancreatic insulin secretion.

The abnormalities disappeared after the participants were allowed to sleep normally again for nine days in the last phase of the study.
